Dim Comp = From C In db.Table1 _
Select C.Completed, C.Taken, C.Namne
Datagridview1.DataSource = Comp
Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.
I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.
how can i change this in code at runtime

View 2 RepliesI have a datagridview that is bound to a binding source.I used the following code to add a checkbox column to the datagridview:
Imports System.Windows.Forms
...
Dim newcolumn as DataGridViewCheckBoxColumn

The checkbox column shows up successfully, but when I try to click any of the checkboxes,nothing happens.The cell remains unchecked.It blinks, so I know that it is acknowledging the click, but the checkbox state does not change.

View 3 RepliesI have a pre-existing database which I am coding to, so I can't change the data stored in the SQL-Server 2005 database. My application uses the DataGridView to maintain the data. There is a yes/no field that I would like to bind a checkbox to. The field is a character field in the database, and holds either Y or N. So, here's the question. I know how to set the column to be a checkbox, I think, but I don't know how to map it so that it reads/stores a "Y" value as checked and a "N" value as unchecked.

i am developing an application in VB.net implies some datagridview operations. the appl contains one DGVW with columns fixed programatically, one such column is Datagridviewcheckbox column. the datasource for dgvw is bounded by a datatable. the user needs to enter the values in the GUI.
supposing the user enters the 2x2 matrix values, and the user checked the checkbox last cell in the dgvw. The problem - the last cell value is not updating inside. if ii debug through code, the "cell(2,2).value" reurns null value whereas the rest of them returns the value what i entered.
if i clicked the mouse some where in the dgvw after entering the last cell value, then it is returning the exact value as expected.
I have a datagridview on my windows form bound to field "STATUS" in SQL database with the default value of 0.What i want to acheive is that for each row in the datagridview, if user clicks the checkbox column only it should display a message " LOCK THE ROW?". If user chooses yes then the entire row should become readonly including the checkbox check "Greyed out" or disabled for that particular row and update value to 1 in the database field.I created checkbox by:
'on form Load_Event
Dim colCheckbox As New DataGridViewCheckBoxColumn()
colCheckbox.AutoSizeMode =DataGridViewAutoSizeColumnMode.ColumnHeader

I'm trying to render a checkbox in a datagridview column header so that when the checkbox is checked/unchecked all the cells in that column should be checked/unchecked accordingly.The datagridview is bound to a database table but the column containing the checkbox header cell is unbound. The problem is, whenever i click the header checkbox, all the cells in that column are checked but the header checkbox itself gets invisible. If I click the HEADER (though the checkbox is invisible, still I can click the header) again, all the cells in the column below are unchecked and the header checkbox becomes visible and unchecked. Everything is happening as expected except the visibility of the header checkbox. Why is it so?

I have a simple datagridview that I fill from a mysql database using the latest mysql connector.net.I configured my columns in the datagridview collection and the data displays fine.I don't want the user to edit data directly in the grid so my datagridview is not readonly but all my columns are except the checkbox one. If I set the datagridview readonly I can't check my checkboxes.I added a checkbox column to be able to delete multiple rows easily but I can't uncheck a checkbox.
Let's say I have 3 rows in my datagridview I check line 1 checkbox- I check line 2 checkbox- I uncheck line 1 checkbox- I check line 3 checkbox As soon as I check line 3 checkbox, line 1 checkbox becomes checked "automagically"
